Return air HVAC registers with slots for filter companions

ABSTRACT

Return air HVAC registers with slots for filter companions is disclosed. A pre-filtered return air register on a HVAC central forced air system, prevents contaminants from entering the system, by filtering the returning air to the HVAC system.

BACKGROUND OF THE INVENTION Problem Solved

Prevents dust, dirt and insects from contaminating return air to central heating and air conditioning systems. Helps keep trunk lines cleaner.

Presently return HVAC central air return registers are open, and allow for all types of contaminants to return into the system.

A pre-filtered return air register on a HVAC central forced air system, prevents contaminants from entering the system, by filtering the returning air to the HVAC system.

DETAILED DESCRIPTION OF THE INVENTION

As stated above, prevents dust, dirt and insects from contaminating return air to central heating and air conditioning systems. Helps keep trunk lines cleaner. The invention claimed here solves this problem.

By having a slot on the internal or external front of a return air register, that accommodates the companion filter, the companion filter then prevents contaminants from returning to the inner parts of the system, such as trunk lines and the like.

The claimed invention differs from what currently exists. Return HVAC central system registers presently do not have a return air filter in place to prevent contaminants.

This invention is an improvement on what currently exists. Return HVAC central system registers presently do not have a return air filter in place to prevent contaminants.

These unfiltered systems allow for dirt, dust, insects and other contaminants to continually compound and create health problems and the need for internal cleaning of these HVAC central forced air systems.

A pre-filtered return air register on a HVAC central forced air system, prevents contaminants from entering the system, by filtering the returning air to the HVAC system.

Also, it can produce cleaner, sanitized, scented or unscented household circulating air.

The Version of the Invention Discussed Here Includes:

1. Slotted standard sized return HVAC forced air return registers, with the slot on the opposite side of the louver adjustment lever, so the filter can be slipped or positioned into the accommodating slot.

Relationship between the Components:

1. A slotted HVAC central system, air return register, with the slot on the opposite side of the louver adjustment lever, the slot made in size to accommodate the accompanying filters to fit the slot 2. Filters sized to fit the slots in #1. the HVAC central systems, air return registers. Filters have a metal, plastic, resin or cardboard border, that holds in place a scented or unscented, paper, mesh metal, plastic or cloth type filter that catches contaminant particles including insects and prevents them from returning into the HVAC central system.

How the Invention Works:

The #1. Slotted HVAC central system air return register is necessary as the slot accommodates the filter sized to fit the accommodating slot. Together they prevent the return of contaminants into the HVAC central forced air system.

Remove old HVAC central air return registers and replace them with #1. Slotted HVAC central system return air registers. Slip sized accommodating filter counterpart into place. Remove and replace filters as desired.

How to Make the Invention:

Make a slot on the opposite side of the louver adjustment level handle of the HVAC central system forced air return register so as to be able to slip into the slotted place, a filter sized to accommodate the slot space of the HVAC central forced air return register.

Both elements are necessary. Neither are optional in order to produce desired results.

Slot jackets could be internal to the HVAC central forced air return registers to accommodate sized filters. Slots could be external to the HVAC central forced air return registers to accommodate sized filters.

How to Use the Invention:

By creating a slotted HVAC central return air register and making a filter sized to accommodate the awaiting slots spaces. Together they would prevent contaminants from returning into the forced air system

Also, it can create: Cleaner, sanitized, scented or unscented household circulating air. 

1. An internal or external placed filter, at the air return register of HVAC systems prevents contaminants from entering the HVAC system.
